Feline Kidney Disease Causes

Kidney disease, also known as chronic renal failure, occurs when a cat's kidneys are not longer able to remove waste products after the digestion of food. Toxins then build up in the blood, which results in kidney failure. Treatment of kidney disease depends on the cause of the disease, and death may occur if a cat does not respond to treatment. Kidney disease may occur in felines for many reasons.

  1. Health Problems

    • According to the Feline CRF Information Center website, high blood pressure, low potassium levels and dental disease may be contributing factors to the development of kidney disease. Other common health-related causes include bacterial infections of the kidneys or cancer of the kidneys. A disease known as glomerulonephritis may also cause kidney disease. Long Beach Animal Hospital reports that bacteria, viruses, cancer and diseases of the internal organs can cause glomerulonephritis. As a result, the kidneys may not filter properly. Lastly, according to Long Beach Animal Hospital, "The FeLV and FIP can affect the kidneys. These viruses are prevalent in the cat world, and cause significant problems."

    Damage to the Kidneys

    • Damage to the kidneys because of severe trauma may also cause kidney disease. Trauma is one of the most common causes of kidney disease and may occur if a car hits a cat.

    Toxins

    • According to Long Beach Animal Hospital website, many toxins, especially antifreeze are disastrous to the kidneys and can result in kidney disease. Other dangerous toxins include pesticides, herbicides, aspirin, anti-inflammatory medications, anesthetics, antibiotics and blood pressure medications. Long Beach Animal Hospital also notes that ingestion of toxins such as antifreeze "is a medical emergency and requires specific and immediate measures if the kidneys are to be saved."

    Breed

    • Some feline breeds are more prone to kidney disease. These breeds include the Maine coon, Abyssinian, Persian, Siamese, Russian blue, Burmese and Balinese.

    Development

    • Kidney disease can affect cats of any age. However, some kittens and younger cats develop congenital renal conditions that are the result of development affecting the kidneys at birth. Outside of these congenital conditions, kidney diseases are more common in older cats. Generally, 9 years is the average age of diagnosis.
